Wheelbarrow kit for 3/4" square tube

Handle and wheel for turning a 3/4" square tube into a wheelbarrow handle. The wheel is designed for optional multi-material printing (I used TPU for the rim and PETG for the hub, with "beam interlocking" enabled in the slicer). The wheel hub takes two 6502 bearings. Max load unknown, but I've had no problem moving a 75Lbs load on 4 foot tubing with a pair of these. Wheel is just under 258mm in diameter and 30mm thick. Handle is 35mm in diameter and covers 100mm from the end of the square tube. I printed in TPU with "fuzzy skin" enabled in and like the feel.
